Hood County Sheriff Roger Deeds says one tornado touched down southeast of Granbury Wednesday night in the Rancho Brazos subdivision, destroying mobile homes and single-family homes. Deeds said at least six residents were reported killed and up to 100 injured, some critically. The injuries range from lost limbs to minor bumps and bruises, Deeds says.
